Electrical and Digital Driven Attenuators

Electrically Controlled Variable Fiber Optics Attenuators

Key Features

  • Stepper motor driven
  • High power handling
  • High speed
  • Wide attenuation range
  • Low PDL and wavelength dependency
  • Low insertion loss and backreflection
  • High resolution
  • Rugged and compact design
  • Can be calibrated for up to five wavelengths

Description

OZ Optics offers a complete line of low cost, compact PC board mountable motor driven variable attenuators with low backreflection. These attenuators offer excellent speed, repeatability and accuracy. Singlemode and polarization maintaining (PM) attenuators utilize a novel blocking style attenuation technique, while multimode attenuators use a variable neutral density filter to minimize mode dependent losses. Both types feature a homing sensor to calibrate the attenuator, removing the need to use external taps, and a jam-proof tuning mechanism.

Applications

  • Active gain equalization in DWDM Systems
  • Local power monitoring and feedback attenuator settings
  • Bit error testing
  • Trouble shooting receivers and other active fiber optic components
  • Simulating long distance fiber transmission
  • Design of fiber optic transmitter/ receiver circuitry
  • Power meter linearity checks
  • Power setting and power control
